Adrenalin - how does this affect blood glucose levels

[Lumpylizzie]

I have an 11 year old son who was diagnosed 12 months ago with Type 1, and I am pleased to say he is adjusting really well to his new life as a diabetic. I say 'new life' because that is exactly what it is. Everything you thought you knew takes on a different meaning, and just when you are preparing yourself to allow your child more independence as a parent you now feel not able to allow as many freedoms. He is adjusting to his mother's worrying and concerns, and he is on the whole very positive.

I am interested to know how adrenalin and stress affects blood sugar levels. We recently went on an active holiday and my son got involved in all sorts of activities, such as kayaking, sailing and water skiing, all which scared him witless but nevertheless he was determined to do everything. However, although he was very active, it was very hot and he ate well and had his normal ratio of insulin to carbs, he was constantly high - readings about 15-18 - most of the week. Normally we would reduce his insulin to prevent hypo's but this was never an issue, in fact it was completely the other way! Can adrenalin and stress, and perhaps excitment, have an impact on BM??

Thanks

Well done him for taking on the diabetes and realising he can still do things and challenge himself despite this new life. Situations that are exciting and or stressful will encourage glucose to be released into the blood stream for the 'fight or flight' response. Before the next adventure like this I would suggest discussing this with your diabetes team so they can give you a plan for the amount if insulin to give him when in these situations.

Hi

Its great your son is keeping active and hope he enjoyed his holiday.

You're quite right usually when patients are active insulin requirments would typically fall. I was interested to hear it was quite hot where you went. If your sons insulin was not stored correctly and in direct sunlight then the effectiveness of his insulin could have been affected resulting in higher than normal glucose levels. It's true that stress can elevate blood glucose levels but I think it's more likely that your sons insulin was affected by the hot weather making it less effective. When travelling to warmer climates it's best to keep the insulin stored in a Frio travel bag to keep it cool.

There are other possible issues which may have contributed. Was your son making accurate carbohydrate estimations. This can often be difficult when eating out or eating foods we're not so familiar with. Was he using correction doses?

Are his injection sites ok? Was there a problem with just the specific batch of insulin he was using?

It would be a good idea if these issues were discussed with his local diabetes specialist team.

Best of luck.
